Inquire about aesthetic procedure planning and budgeting

Hello, friends! I'm Zaya from Ulaanbaatar. I'm in the initial stages of planning to visit Seoul later this year for aesthetic procedures. However, I'm very uncertain about the planning and budgeting. I don't know how to properly budget for this trip, as I'm unsure how many days it should last, depending on moving costs, accommodation expenses, recovery time after the procedure, and language barriers.

Currently, I'm listening to advice from people who have been there. Many of them say 5-7 days is enough, but I don't know if this is a good value or if I can trust it. How should I start budgeting for the types of procedures? Do you have any suggestions or experiences regarding your own planning? I'm asking people for their opinions because I don't know what I don't know.
